[sovereign] Fix resync cross chain data integrity checks

[mariusmihaic]

Reasoning behind the pull request

• When a node was re-syncing the network while there were cross chain mbs/headers/scrs, validity checks for intercepted data would fail

Proposed changes

• Refactored validity/integrity checks like checkMiniBlocksHeaders & CheckValidity to accept core.MainChainShardID as valid shard ID

Testing procedure

Pre-requisites

Based on the Contributing Guidelines the PR author and the reviewers must check the following requirements are met:

• was the PR targeted to the correct branch?
• if this is a larger feature that probably needs more than one PR, is there a feat branch created?
• if this is a feat branch merging, do all satellite projects have a proper tag inside go.mod?
